REGISTERENG MECHANISM FOR PRINTING-PRESSES.

SPECIFICATION forming part of Letters Patent No. 577,555, dated February23, 1897.

Application filed May 28, 1892. Serial No. 434,814. (No model.)

To all whom it may concern:

Be it known that I, WINFIELD S. I-lUsoN, a citizen of the United States,residing at Taunton, in the county of Bristol and State ofMassachusetts, have invented a new and useful Improvement in RegisteringMechanism for Printing-Presses, of which the following is aspecification.

The aim of this invention is to produce a new and improved registeringmechanism for printing-presses which will secure absolute and perfectregister between the impressioncylinder and reciprocating bed of theprinting-press.

The invention is especially designed and adapted for use in connectionwith the two or multi revolution single or multi cylinderprinting-press, though of course the same may be adopted for use withany form of cylinder-press, and with this understanding I will furtherdescribe my invention as applied to the ordinary well-knowntwo-revolution single-cylinder printing-press.

My invention consists of the device described in this specification andillustrated in the accompanying drawings, in which Figure l is a sideelevation of enough of a two-revolution sin gle-cylinder printing-pressto illustrate my invention. Fig. 2 is a sectional elevation at rightangles to Fig. 1.

Referring to the drawings and in detail, A represents the usual framingof the printingpress, in which are j ournaled the usual eccentricbushings B, and in these eccentric bushings B is journaled or mountedthe shaft 0, upon which the impression cylinder D is mounted. On theshaft 0 is loosely mounted the registering-gear E, as shown, andprojecting from the side face of the cylinder D are pins or'studs F,which fit in holes bored into bosses on the gear E, as shown. Thus itwill be seenthat impression-cylinder D and registering-gear E are tiedtogether, but that the gear E may be shifted laterally on the shaft 0. Akeyway cut in the shaft 0 is equivalent to this construction',.but thepins shown are preferred because they are stronger and more of them canbe used, and by the use of the same the connection is brought as near tothe teeth of the gear E as possible.

G represents the usual reciprocating bed. A registering-rack H isattached to the same by means ofbolts h. Bolted to the side of the rackH is a guard I, the top of which projects slightly above the teeth ofthe rack.

The usual driving-gear J is mounted on the outside of the shaft 0, andby means of the same the impression-cylinder D is rotated.

K represents the usual oscillating shaft, which is connected by arms orlevers L and links or connect-ions M to the arms b of the eccentricbushings B.

It will be seen that in the particular device under consideration thecenter 1) of the bushings B is placed next to the rod M and that thecenter of the shaft 0 is placed on the other side of center 6 from thelinks M. By this arrangement when links M are pulled down theimpression-cylinderD will be raised, and when links M are pushed up theimpression-cylinder D will be lowered.

Fastened to the hub of the gear E is a yoke N, which is fitted laterallyon the gear E, but which is independent circumferentially of the gear,whereby the yoke N may remain stationary and the gear E revolve.

The yoke N is connected by two links 0 to the levers Q, which aremounted on a small transverse shaft P, which is journaled on the insideof the frame, as shown, and on one end of this shaft is attached thelever or arm T, which has an open mouth, as shown.

Fastened on one of the links M is block R, which has a projecting pin S,which engages the mouth of lever T.

A starter-segment U of the usual form is secured to the side of theimpression-cylinder D inside of the registering-gear, as shown, and thesame cooperates in the usual manner with the short starter-rack V tostart the bed and impression-cylinder in proper register. This startersegment and rack are not necessary in all constructions, but may be usedon some of the larger forms of presses.

The operation of my device is apparent and 9 as follows: The parts areshown in the draw-. ings with the bed commencing its forward or printingstroke, the impression-cylinder D lowered to coact with the bed, and theregistering-gear moved in toward the cylinder D to foo cooperate withthe registering-rack II. Now when the bed has completed its forwardstroke to the left the rack II will be beyond the gear E, so that thegear E may be shifted laterally. Now when the bed is at its extreme theshaft K is oscillated and the links M pulled down. This, as beforedescribed, will raise the impression-cylinder D, so that the same willclear the bed G as the bed makes its retrograde stroke; also, by meansof the links and connections before described by the downward movementof the links M the gear E will be shifted laterally to disengage fromthe rack II, or out of the vertical plane of said rack. Then when thebed makes its retrograde movement the impression-cylinder D will beraised from the bed, and the gear E will be out of mesh with the rackII. hen the bed has completed its retrograde movement, the links M willbe raised and impression-cylinder D lowered and the registeringgcar Emoved in to engage the registeringrack II, or into the plane of saidregisteringrack. The bed has the usual amount of stroke, so that as thebed is at its extremes in either direction the rack II will be beyondthe registering-gear E.

Thus it will be seen that I have invented a device by which the cylinderand bed may be nicely kept in absolute register on the printin g strokeand by which the same are entirely independent on the retrograde strokeof the bed.

The guard I, mounted on the side of the rack I1, is useful and importantin that it prevents gear E, when in mesh with the rack H, from slidingout of mesh, and also in that it prevents gear E, when the same is outof mesh, from accidentally moving inwardly to engage the rack I, andthus breaking the teeth of the registering mechanism.

The details and arrangements of parts herein shown and described may bevaried by a skilled mechanic without departing from the scope of myinvention as expressed in the claims.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

1. In a cylinder printing-press, the combination of theimpression-cylinder having a registering-gear connected to turn thesame, the reciprocating bed, having a registeringrack adapted to coactwith said registeringgear, and means for shifting said gear laterally sothat the rack and gear will be in mesh on one stroke and out of mesh 011the other stroke of the bed, substantially as described.

2. In a cylinder printing-press, the combin ation of theimpression-cylinder, havinga registering-gear connected to turn with thesame, the reciprocating bed having a registeringrack mounted on thesame, means for moving said gear laterally so that the same willalternately engage and disengage with said registering-rack, and a guardas I secured to the side of said rack, substantially as described.
